users192.168.2.8:8000/users
访问它

所以我的 API 网关看起来像这样:

package main

import (
    "github.com/codegangsta/martini"
    "net/http"
)

func main(){
    app := martini.Classic()
    app.Get("/users/:resource", func(req *http.Request, res http.ResponseWriter){
        //proxy to http://192.168.2.8:8000/:resource
    })
    app.Run()
}

[vhost v2] release 2.2.5
package main

import(
    "net/url"
    "net/http"
    "net/http/httputil"
    "github.com/codegangsta/martini"
    "fmt"
)

func main() {
    remote, err := url.Parse("http://127.0.0.1:3000")
    if err != nil {
        panic(err)
    }

    proxy := httputil.NewSingleHostReverseProxy(remote)
    app := martini.Classic()
    app.Get("/users/**", handler(proxy))
    app.RunOnAddr(":4000")
}

func handler(p *httputil.ReverseProxy) func(http.ResponseWriter, *http.Request, martini.Params) {
    return func(w http.ResponseWriter, r *http.Request, params martini.Params) {
        fmt.Println(params)
        r.URL.Path = "/authorize"
        p.ServeHTTP(w, r)
    }
}
